G Only something with no mass (such as light) can move at the speed of light. b. Theoretically, a particle with mass can only move faster than the speed of light if given infinite energy. c. When in a medium (such as water) light will move less than c, and observers in different inertial frames can observe that light moving at different speeds. d. Theoretically, a particle with mass can only reach the speed of light if given infinite energy. e. Choices a), c), d) are correct.

true a and c

Explanation:

The theory of special relativity is formulated under two postulates

* that the laws of physics are the same in all inertial systems

* that the speed of light in the vacuum is constant for all systems

with these postulates the energy of a particular is

        E = K + m c²

where the last term is called energy at rest

a) True. only when m = 0 the energy of the particle is scientific energy

be False. Nothing can go faster than light

c) Right. In a material medium the speed of light depends on the measurement reference frame

d) False For a particle of finite mass the energy must be greater than the energy at rest

good looking response

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
